So what you're saying is that a white actor should always be cast to play any character that was originally white whether they are the best actor or not?

Keep in mind historical figures are largely white because of systemic racism and in your scenario the film and television industry would have to purposefully double down on the discrimination that empowered those people to meet your requirements.

I'm not defending Google's ham fisted approach. But at the same time it's a great reinforcement of the reality that Large Language Models cannot and should not be relied upon for accurate information. LLMs are just as ham fisted for accurate information as Google's approach to diversity in LLMs.
